any suggestions on how i can switch her over to rats instead.

Try scenting an apropriately sized rat. If your feeding F/T get a scoop of used,stinky,mouse beeding from the pet store (they should have no problem giving it to you). Thaw the rat out in a zip lock bag with the smelly mouse bedding. Get the rat realy warm and rubb the mouse bedding all over it, getting the rat stinky with the mouse bedding. Than serve dinner

.
It may take a few trys but its a realy good method to switch over those finicky eaters.
Hope this helps.
